Description

Panneau préfabriqué pour construction de bâtiment et procédé de fabrication d'un tel panneau Prefabricated panel for building construction and method of manufacturing such a panel
La présente invention concerne le domaine de la construction de bâtiments à partir de panneaux préfabriqués et concerne plus particulièrement le panneau préfabriqué en tant que tel, l'assemblage de plusieurs panneaux entre eux et les procédés de fabrication desdits panneaux ainsi que la construction du bâtiment à partir de ces panneaux préfabriqués.The present invention relates to the field of the construction of buildings from prefabricated panels and more particularly concerns the prefabricated panel as such, the assembly of several panels together and the manufacturing processes of said panels and the construction of the building to from these prefabricated panels.
Parmi les critères importants de qualité d'une construction figurent en bonne place la résistance mécanique et l'isolation thermique des murs formant l'enveloppe extérieure du bâtiment. Ces critères peuvent être satisfaits par l'utilisation de deux matériaux à propriétés opposées mais complémentaires que sont le béton armé et le polystyrène expansé.Among the important quality criteria of a building are the mechanical strength and the thermal insulation of the walls forming the outer shell of the building. These criteria can be satisfied by the use of two materials with opposing but complementary properties that are reinforced concrete and expanded polystyrene.
En effet, d'une part le béton armé est de faible coût, de mise en œuvre facile, présente une très bonne résistance mécanique et est ininflammable mais présente l'inconvénient d'un poids élevé et d'une mauvaise isolation thermique.Indeed, on the one hand the reinforced concrete is low cost, easy to implement, has a very good mechanical strength and is nonflammable but has the disadvantage of a high weight and poor thermal insulation.
En revanche, le polystyrène expansé, qui est également de faible coût, présente une excellente isolation thermique, un poids très faible mais a pour inconvénient d'être inflammable et de posséder une très mauvaise résistance mécanique. Parmi les procédés de mise en œuvre simultanée de ces deux matériaux dans la construction de bâtiments, on peut citer :In contrast, expanded polystyrene, which is also low cost, has excellent thermal insulation, a very low weight but has the disadvantage of being flammable and having a very poor mechanical strength. Among the methods of simultaneous implementation of these two materials in the construction of buildings, there may be mentioned:
Une méthode qui consiste à monter sur le site de construction des panneaux en polystyrène, à placer autour de ces panneaux un ferraillage puis à projeter du béton sur chacune des faces du panneau en polystyrène. Une autre méthode comprend la mise en place de deux panneaux de polystyrène parallèles servant de coffrage, l'incorporation d'entretoises et d'armatures métalliques, puis le coulage de béton à l'intérieur de l'espace formé par les deux panneaux, puis l'enduction des faces extérieures du polystyrène avec du béton. Encore une autre méthode consiste à utiliser des blocs de polystyrène en forme de parpaings, à placer des renforts métalliques à l'intérieur des alvéoles des parpaings et à couler à l'intérieur du béton, l'ensemble étant ensuite recouvert extérieurement de béton. Les inconvénients majeurs de ces méthodes sont les suivants. Tout d'abord, au cours de la construction la partie polystyrène est visible, ce qui est un obstacle important au développement de ce type de construction car le polystyrène expansé est dans l'esprit du public un matériau bas de gamme avec une image de grande fragilité. En outre, ces murs ne sont pas reproduits de façon identique puisqu'ils sont fabriqués sur site, en particulier la couche de béton de revêtement n'est pas uniforme et difficilement reproductible d'un mur à un autre, d'une construction à une autre. De plus lorsque le polystyrène expansé sert de coffrage, il est nécessaire de prévoir des éléments de guidage pour leur montage ou des armatures et des entretoises qui sont à l'origine de ponts thermiques.A method consisting in mounting polystyrene panels on the construction site, placing a reinforcement around these panels and then spraying concrete on each of the polystyrene panel faces. Another method involves the installation of two parallel polystyrene panels used as formwork, the incorporation of spacers and metal reinforcements, then the pouring of concrete inside the space formed by the two panels, then the coating of the outer faces of the polystyrene with concrete. Yet another method is to use blocks of polystyrene in the form of blocks, to place metal reinforcements inside the cells of the blocks and to flow inside the concrete, the assembly then being externally covered with concrete. The major disadvantages of these methods are as follows. First of all, during construction the polystyrene part is visible, which is a major obstacle to the development of this type of construction because expanded polystyrene is in the mind of the public a low-end material with a large image. fragility. In addition, these walls are not reproduced identically since they are manufactured on site, especially the coating concrete layer is not uniform and difficult to reproduce from one wall to another, a construction to a other. In addition, when the expanded polystyrene serves as formwork, it is necessary to provide guide elements for their assembly or reinforcements and spacers that are at the origin of thermal bridges.
La présente invention a donc pour but de pallier les inconvénients précités en proposant un procédé de construction associant l'utilisation de béton armé et de polystyrène expansé, de mise en œuvre simple en évitant la création de ponts thermiques qui nuisent à l'isolation thermique des murs fabriqués.The present invention therefore aims to overcome the aforementioned drawbacks by proposing a construction method combining the use of reinforced concrete and expanded polystyrene, simple implementation avoiding the creation of thermal bridges that affect the thermal insulation of manufactured walls.
Un autre but de l'invention est de proposer un procédé de réalisation de murs pour des bâtiments à faible coût et totalement reproductible.Another object of the invention is to provide a method of making walls for buildings at low cost and fully reproducible.
A cet effet, il a été envisagé de concevoir un panneau préfabriqué en usine comprenant une âme en matériau isolant de type polystyrène expansé recouverte sur ses deux faces d'une couche de béton.For this purpose, it has been envisaged to design a prefabricated factory panel comprising a core of expanded polystyrene type insulating material covered on both sides with a layer of concrete.
De tels panneaux ont été décrits notamment dans les brevetsSuch panels have been described in particular in patents
DE 3242364 ou US 4 669 240, cependant ces éléments modulaires présentent soit des entretoises métalliques pour retenir les deux parois extérieures du panneau, soit des armatures métalliques faisant communiquer entre elles ces deux parois, des ponts thermiques sont donc présents dans ces modules. De même, le module décrit dans le brevet US 5 697 189, formé d'un panneau en béton muni d'alvéoles internes remplies de polystyrène expansé, présente l'inconvénient que le béton communique d'une face à l'autre.DE 3242364 or US 4,669,240, however these modular elements have either metal spacers to retain the two outer walls of the panel, or metal reinforcements communicating with each other these two walls, thermal bridges are present in these modules. Similarly, the module described in US Patent 5,697,189, formed of a concrete panel provided with internal cells filled with expanded polystyrene, has the disadvantage that the concrete communicates from one face to the other.
Ces liaisons en béton internes sont également à l'origine de ponts thermiques indésirables.These internal concrete connections also cause unwanted thermal bridges.
Un autre but de l'invention est donc de concevoir des panneaux préfabriqués et un assemblage de ces panneaux exempt de ponts thermiques, tout en présentant une grande résistance mécanique et une grande légèreté.Another object of the invention is therefore to design prefabricated panels and an assembly of these panels free of thermal bridges, while having a high mechanical strength and great lightness.
A cet effet, la présente invention concerne donc tout d'abord un panneau préfabriqué pour construction de bâtiment comprenant une âme pleine en matériau isolant sous la forme d'une plaque recouverte sur ses deux faces d'une couche de béton uniforme caractérisé en ce que dans ladite plaque formant l'âme sont ménagés :For this purpose, the present invention therefore firstly relates to a prefabricated panel for building construction comprising a solid core of insulating material in the form of a plate covered on both sides with a uniform concrete layer characterized in that in said plate forming the core are formed:
- d'une part au voisinage d'une face de la plaque une première série de logements pour des éléments de renfort constituant des montants à l'état dressé du panneau sur le sol, et faisant saillie à au moins une de leurs extrémités en vue de leur scellement au sol, eton the one hand, in the vicinity of one face of the plate, a first series of housings for reinforcing elements constituting amounts in the erected state of the panel on the ground, and projecting from at least one of their ends in order to grounding them, and
- d'autre part sur la face opposée de la plaque une seconde série de logements pour des éléments de renfort s'étendant entre deux bords parallèles du panneau et faisant saillie au-delà de ces bords de manière à constituer un élément de ceinture, à l'état assemblé dudit panneau avec des panneaux adjacents.on the opposite side of the plate, a second series of housings for reinforcement elements extending between two parallel edges of the panel and projecting beyond these edges so as to constitute a belt element, the assembled state of said panel with adjacent panels.
Ce panneau préfabriqué comprenant des éléments de raccord avec des panneaux adjacents permet de réaliser dans un temps très rapide la construction de bâtiments dont les murs, notamment les murs extérieurs, sont constitués de tels panneaux. La plaque en matériau isolant étant recouverte en usine sur ses deux faces d'une couche de béton, le matériau isolant est masqué et n'est nullement apparent lors de la construction. Par ailleurs, l'application de béton pouvant être effectuée à plat en usine, l'épaisseur de ces couches de béton est uniforme et très reproductible d'un panneau à un autre. Il est donc possible de garantir pour tous les panneaux des propriétés identiques en terme de résistance mécanique ou d'isolation thermique, par exemple.This prefabricated panel comprising connecting elements with adjacent panels makes it possible to achieve in a very rapid time the construction of buildings whose walls, including the outer walls, are made of such panels. The insulating material sheet is covered in the factory on both sides with a layer of concrete, the insulating material is masked and is not visible during construction. Furthermore, the application of concrete can be carried out flat in the factory, the thickness of these concrete layers is uniform and very reproducible from one panel to another. he It is therefore possible to guarantee for all panels identical properties in terms of mechanical strength or thermal insulation, for example.
De manière avantageuse, la première de série de logements et la seconde série de logements ménagés dans la plaque formant l'âme du panneau sont exemptes de zone de communication entre elles afin d'éviter la formation de ponts thermiques. Ainsi les renforts disposés sur une face sont écartés des éléments de renfort disposés sur l'autre face de l'âme en matériau isolant. En outre, il n'existe aucune zone de communication entre les deux couches extérieures de béton. Les logements sont avantageusement réalisés sous forme de rainures dont les axes longitudinaux sont orthogonaux d'une série à une autre. Ces rainures peuvent soit affleurer la surface extérieure de la plaque en matériau isolant ou déboucher à la surface de cette plaque.Advantageously, the first series of housings and the second series of housings formed in the plate forming the core of the panel are free of communication zone between them to prevent the formation of thermal bridges. Thus the reinforcements arranged on one side are spaced apart from the reinforcing elements arranged on the other face of the core of insulating material. In addition, there is no communication zone between the two outer layers of concrete. The housings are advantageously made in the form of grooves whose longitudinal axes are orthogonal from one series to another. These grooves may either be flush with the outer surface of the insulating material plate or open on the surface of this plate.
Les éléments de renfort sont de préférence des éléments métalliques. Un treillis, de préférence métallique, peut être appliqué sur ou être disposé parallèlement à chaque face de la plaque formant l'âme du panneau à proximité immédiate de celle-ci. De préférence, les éléments de renfort peuvent servir également de support à ce treillis. Les dimensions de ce treillis correspondent avantageusement à la surface de chacune des faces de la plaque.The reinforcing elements are preferably metal elements. A trellis, preferably metal, may be applied to or parallel to each face of the plate forming the core of the panel in close proximity thereto. Preferably, the reinforcing elements can also serve as a support for this mesh. The dimensions of this mesh advantageously correspond to the surface of each of the faces of the plate.
Afin de pouvoir assembler les panneaux entre eux en formant un angle, il est avantageux que les tranches du panneau soient, au moins partiellement, biseautées pour s'adapter aux panneaux adjacents en formant un assemblage de type assemblage à onglet, interrompu pour ménager une zone d'angle libre permettant la liaison entre les éléments de ceinture de deux panneaux adjacents. Dans le cas où une couche de béton recouvre la tranche biseautée, il peut être avantageux, pour éviter la création d'un pont thermique via le béton, de prévoir une tranche biseautée discontinue, à savoir l'incorporation d'une bande de matériau isolant transversalement à ladite tranche. De manière préférée, l'âme est en polystyrène expansé, de préférence haute densité, ou en mousse rigide à cellules fermées. Les faces de la plaque formant l'âme présentent, de préférence des surfaces striées, pour une meilleure adhésion du béton sur celles-ci.In order to be able to join the panels together at an angle, it is advantageous that the panels of the panel are at least partially bevelled to fit the adjacent panels forming a miter assembly assembly, interrupted to provide a zone of free angle allowing the connection between the belt elements of two adjacent panels. In the case where a layer of concrete covers the beveled edge, it may be advantageous, to avoid the creation of a thermal bridge via the concrete, to provide a discontinuous beveled slice, namely the incorporation of a strip of insulating material transversely to said slice. Preferably, the core is expanded polystyrene, preferably high density, or rigid closed cell foam. The faces of the plate forming the core have, preferably striated surfaces, for a better adhesion of concrete thereon.
Le panneau ainsi fabriqué est de faible coût, et présente une bonne résistance mécanique ainsi qu'une excellente isolation thermique. En outre, l'âme pouvant être d'épaisseur importante, ce panneau est de poids très réduit par rapport aux panneaux préfabriqués existants. Il est donc facilement transportable jusque sur les sites de construction. Le poids réduit de ces panneaux entraîne également la limitation de l'épaisseur des fondations nécessaires pour supporter ces panneaux. La présente invention concerne également un assemblage de panneaux préfabriqués pour construction de bâtiment tel que décrit précédemment, les éléments de renfort s'étendant entre deux bords parallèles du panneau étant logés dans des rainures horizontales ménagées dans l'âme du panneau, sur sa face tournée vers l'extérieur du bâtiment, de manière, après liaison des extrémités saillantes des éléments de renfort de panneaux adjacents, à former un ceinturage horizontal de la construction, en constituant ainsi une structure de type auto-portée. Une telle structure est stable, rigide et indéformable.The panel thus manufactured is of low cost, and has good mechanical strength and excellent thermal insulation. In addition, the core may be of significant thickness, this panel is very small weight compared to existing prefabricated panels. It is therefore easily transportable to construction sites. The reduced weight of these panels also limits the thickness of the foundations required to support these panels. The present invention also relates to an assembly of prefabricated panels for building construction as described above, the reinforcement elements extending between two parallel edges of the panel being housed in horizontal grooves formed in the core of the panel, on its turned side. to the outside of the building, so, after connecting the projecting ends of the reinforcing elements of adjacent panels, to form a horizontal belt of the construction, thereby constituting a self-supported type structure. Such a structure is stable, rigid and indeformable.
La présente invention est également relative à un procédé de fabrication de panneau préfabriqué tel que décrit précédemment, comprenant les étapes successives suivantes :The present invention also relates to a prefabricated panel manufacturing method as described above, comprising the following successive steps:
- découpe de plaque de polystyrène expansé, en ménageant d'une part une première série de rainures parallèles entre elles sur une face de la plaque et d'autre part une seconde série de rainures parallèles sur l'autre face de la plaque, les axes longitudinaux des rainures étant orthogonaux d'une série à l'autre et des tranches de la plaque partiellement biseautées,- cutting expanded polystyrene plate, by providing on the one hand a first series of grooves parallel to each other on one side of the plate and secondly a second series of parallel grooves on the other side of the plate, the axes longitudinal grooves being orthogonal from one series to another and slices of the plate partially bevelled,
- incorporation des éléments de renfort dans leurs rainures respectives, en laissant leurs extrémités saillantes au-delà des bords de la plaque, - fixation d'un treillis, de préférence métallique, sur chaque face de la plaque, avec accroche du treillis sur les éléments de renfort, afin de former une plaque renforcée,- incorporation of the reinforcing elements in their respective grooves, leaving their projecting ends beyond the edges of the plate, - Fixing a mesh, preferably metal, on each side of the plate, with hanging lattice on the reinforcing elements, to form a reinforced plate,
- coulage d'une couche uniforme de béton auto-lissant sur une face de ladite plaque renforcée puis séchage du béton,pouring a uniform layer of self-leveling concrete onto one side of said reinforced plate and then drying the concrete,
- coulage d'une couche uniforme de béton auto-lissant sur l'autre face de ladite plaque renforcée, puis séchage du béton.pouring a uniform layer of self-leveling concrete onto the other side of said reinforced plate, and then drying the concrete.
Ce procédé très simple est aisément réalisable en usine.This very simple process is easily done in the factory.
La présente invention concerne également un procédé de construction de bâtiment à partir de tels panneaux préfabriqués, incluant le procédé de fabrication ci-dessus, et comprenant en outre :The present invention also relates to a building construction method from such prefabricated panels, including the manufacturing method above, and further comprising:
- le placement vertical de chaque panneau et le scellement dans le sol des extrémités saillantes des éléments de renfort formant montants verticaux, les logements des éléments de ceinture se trouvant disposés horizontalement sur la face du panneau tournée vers l'extérieur du bâtiment à construire,the vertical placement of each panel and the sealing in the ground of the projecting ends of the reinforcing elements forming vertical uprights, the housings of the belt elements being arranged horizontally on the face of the panel facing the outside of the building to be constructed,
- rapprochement et mise en contact des tranches biseautées de panneaux adjacents,- bringing together and bringing into contact beveled slices of adjacent panels,
- mise en place de la liaison entre les extrémités saillantes correspondantes des éléments de ceinture disposés horizontalement, au niveau des zones d'angle libres entre les panneaux adjacents, en créant un ceinturage complet de la construction.- Establishment of the connection between the corresponding projecting ends of the belt elements arranged horizontally at the free corner areas between the adjacent panels, creating a complete belting of the construction.
De manière avantageuse, dans la zone d'angle libre entre deux panneaux adjacents est disposée une armature verticale, de préférence métallique, à laquelle sont solidarisées les extrémités saillantes des éléments de renfort horizontaux.Advantageously, in the zone of free angle between two adjacent panels is disposed a vertical armature, preferably metal, which are secured to the projecting ends of the horizontal reinforcing elements.
De plus autour de la zone d'angle libre entre deux panneaux adjacents peut être disposé un coffrage permettant d'y couler du béton. Ce procédé de construction est donc très simple et très rapide à mettre en œuvre. La construction ainsi réalisée est, outre ses propriétés de résistance mécanique et d'isolation thermique, très bon marché.In addition, around the free-angle zone between two adjacent panels may be placed a formwork for pouring concrete therein. This construction process is very simple and very quick to implement. The construction thus produced is, in addition to its mechanical strength and thermal insulation properties, very cheap.
Les murs ainsi réalisés permettent d'y adapter des toits classiques (charpentes et couvertures) et peuvent être aisément recouverts d'un enduit de finition classique.The walls thus made make it possible to adapt conventional roofs (frameworks and covers) and can be easily covered with a conventional finishing plaster.
Des ouvertures, telles que portes et fenêtres, peuvent être disposées en usine dans ledit panneau. En outre, la plaque en matériau isolant constituant l'âme peut être également découpée ou usinée afin de ménager des gaines pour des câbles électriques ou des tuyauteries. Il ne restera plus qu'à effectuer sur le site les raccordements de ces câbles ou tuyauteries.Openings, such as doors and windows, can be arranged at the factory in said panel. In addition, the plate of insulating material constituting the core can also be cut or machined to provide ducts for electrical cables or pipes. All that remains is to carry out on the site the connections of these cables or pipes.
Les extrémités supérieures des éléments de renfort verticaux peuvent faire saillie du bord supérieur du panneau de manière à constituer des éléments d'accroché (par exemple pour des élingues) en vue de la manutention et du transport dudit panneau en usine et sur le site de construction. Ces extrémités saillantes peuvent également permettre le raccordement ou la fixation audit panneau de divers autres éléments de construction, notamment des éléments de toiture.The upper ends of the vertical reinforcing elements may protrude from the upper edge of the panel so as to constitute hooking elements (for example for slings) for handling and transporting said panel at the factory and on the construction site. . These projecting ends may also allow the connection or attachment to said panel of various other building elements, including roof elements.
La présente invention concerne également un bâtiment construit par le procédé ci-dessus caractérisé en ce que les murs extérieurs sont constitués par un assemblage de panneaux préfabriqués tel que décrit précédemment.The present invention also relates to a building constructed by the above method characterized in that the outer walls are constituted by an assembly of prefabricated panels as described above.
D'autres particularités et avantages ressorti ront de la description ci-après d'un exemple non limitatif de réalisation de l'invention en référence aux figures annexées sur lesquelles : la figure 1 est une vue de dessus longitudinale d'un panneau conforme à la présente invention ; la figure 2 est une vue de dessus partielle d'un assemblage de trois panneaux adjacents conforme à la présente invention ; la figure 3 est une vue de face de l'assemblage selon la figure 2. Comme représenté sur la figure 1 , un panneau conforme à la présente invention est constitué d'une âme 2, de préférence en polystyrène expansé, prise en sandwich entre deux couches 3A (couche extérieure) et 3B (couche intérieure) de béton. L'âme 2 forme une plaque qui peut être constituée elle- même d'un assemblage de blocs de polystyrène collés entre eux, comme visibles sur les figures 1 et 3, et référencés 2a, 2b, 2c, 2d... (Les mots "intérieur" et "extérieur" font, dans l'ensemble du texte, référence au positionnement des faces du panneau lors de la construction du bâtiment).Other features and advantages will emerge from the following description of a non-limiting embodiment of the invention with reference to the appended figures in which: Figure 1 is a longitudinal top view of a panel according to the present invention; Figure 2 is a partial top view of an assembly of three adjacent panels according to the present invention; FIG. 3 is a front view of the assembly according to FIG. 2. As shown in Figure 1, a panel according to the present invention consists of a core 2, preferably expanded polystyrene, sandwiched between two layers 3A (outer layer) and 3B (inner layer) of concrete. The core 2 forms a plate which may itself consist of an assembly of polystyrene blocks bonded together, as visible in Figures 1 and 3, and referenced 2a, 2b, 2c, 2d ... (The words "inside" and "outside" are, throughout the text, reference to the positioning of the faces of the panel during the construction of the building).
Dans la plaque formant l'âme 2 sont ménagés, à proximité de sa face intérieure, des logements 4 parallèles entre eux constitués de rainuresIn the plate forming the core 2 are formed, near its inner face, housing 4 parallel to each other consisting of grooves
(verticales lorsque le panneau est dressé sur le sol). Ces logements 4 représentés ici sur la figure 1 comme débouchant à la face intérieure de l'âme(vertical when the panel is erected on the ground). These housings 4 shown here in Figure 1 as opening to the inner face of the soul
2, reçoivent des renforts métalliques 5 tenus en place dans le logement par des cales (non représentées). A ces renforts verticaux 4 est fixé le treillis intérieur 6 disposé parallèlement à la face intérieure de l'âme 2. Lors de l'application de béton auto-lissant sur la face intérieure de l'âme 2, ce béton forme la couche intérieure de béton 3B et remplit également les rainures formant les logements2, receive metal reinforcements 5 held in place in the housing by wedges (not shown). To these vertical reinforcements 4 is fixed the inner mesh 6 arranged parallel to the inner face of the core 2. When applying self-leveling concrete on the inner face of the core 2, this concrete forms the inner layer of 3B concrete and also fills the grooves forming the dwellings
4 en noyant le treillis 6 et les renforts verticaux 4.4 by embedding the lattice 6 and the vertical reinforcements 4.
Sur la face extérieure de l'âme 2, sont découpés des logements 7 (horizontaux lorsque le panneau est dressé sur le sol) destinés à recevoir les éléments de renfort 8 horizontaux. Un treillis 9 extérieur est disposé parallèlement à la face extérieure de la plaque formant l'âme 2. Ce treillis est relié par de multiples liaisons 10 aux éléments de renfort horizontaux 8, pour le maintenir en place en particulier lors du coulage du béton, et l'écarter (d'une faible distance) de la face extérieure de l'âme 2On the outer face of the core 2, are cut housing 7 (horizontal when the panel is erected on the floor) for receiving the horizontal reinforcing elements 8. An outer lattice 9 is arranged parallel to the outer face of the plate forming the core 2. This lattice is connected by multiple connections 10 to the horizontal reinforcing elements 8, to hold it in place, in particular during pouring of the concrete, and remove it (from a short distance) from the outer face of the soul 2
Lorsque le béton de la couche 3A est coulé sur la face extérieure de l'âme 2, ce béton remplit également les interstices laissés dans les logements 7 autour de l'élément de renfort 8 et enrobe l'élément de renfort 8 et le treillis extérieur 9. L'écartement des treillis intérieur 6 et extérieur 9 des faces respectives de la plaque en polystyrène peut aussi être réalisé au moyen de nervures ou de bossages ménagés à la surface de la dite plaque, de manière à ce que les treillis soient quasi entièrement enrobés dans le béton.When the concrete of the layer 3A is poured on the outer face of the core 2, this concrete also fills the interstices left in the housing 7 around the reinforcing element 8 and coats the reinforcing element 8 and the outer trellis 9. The spacing of the inner 6 and outer 9 mesh of the respective faces of the polystyrene plate can also be achieved by means of ribs or bosses formed on the surface of said plate, so that the lattices are almost completely embedded in the concrete.
Les rainures servant de logement aux renforts métalliques 5 et 8 peuvent présenter diverses formes, par exemple en U, en T, en queue d'aronde, etc.. : elles servent aussi de moules pour le béton qui y est coulé.The grooves serving as a housing for the metal reinforcements 5 and 8 may have various shapes, for example U-shaped, T-shaped, dovetailed, etc.: they also serve as molds for the concrete poured therein.
Pour remplir lesdits logements et former les couches recouvrant chaque face de l'âme 2, le béton, de préférence auto-lissant, peut être coulé en une seule fois, ou en plusieurs fois ; dans ce dernier cas, il est possible d'utiliser des bétons de natures différentes. Les éléments de renfort 5 et 8 peuvent être constitués d'une tige ou d'un profilé unique, ou avantageusement, comme dans l'exemple présenté sur les figures 1 et 2, d'un assemblage de plusieurs tiges (ici quatre) reliées entre elles par des entretoises par exemple de type zigzag, comme de manière classique sur les chantiers de construction mettant en ouvre du béton armé. Les tranches verticales du panneau 1 sont partiellement biseautées 11 , ici à 45°. Cette forme en biseau 11 permet au panneau 1 , de s'appliquer contre deux panneaux adjacents 21 ou 22, comme visible sur la figure 2. La zone d'angle laissée alors libre 12 entre deux panneaux adjacents est un espace permettant de joindre les éléments de renfort horizontaux de deux panneaux adjacents et de les lier par exemple par soudure entre eux et/ou à une armature 13 positionnée verticalement comme représenté sur la figure 2. Une telle liaison entre deux panneaux adjacents rigidifie considérablement la structure.To fill said housings and form the layers covering each face of the core 2, the concrete, preferably self-leveling, can be cast at once, or in several times; in the latter case, it is possible to use concretes of different natures. The reinforcing elements 5 and 8 may consist of a rod or a single profile, or advantageously, as in the example shown in Figures 1 and 2, an assembly of several rods (here four) connected between they by zigzag type spacers, such as conventionally on construction sites implementing reinforced concrete. The vertical slices of the panel 1 are partially bevelled 11, here at 45 °. This beveled shape 11 allows the panel 1, to be applied against two adjacent panels 21 or 22, as can be seen in FIG. 2. The left-angle zone then left free between two adjacent panels is a space for joining the elements horizontal reinforcement of two adjacent panels and bind them for example by welding them and / or a frame 13 positioned vertically as shown in Figure 2. Such a connection between two adjacent panels significantly stiffens the structure.
Après assemblage de deux panneaux adjacents selon l'invention, un coffrage 14 peut être installé autour la zone d'angle 12 de manière à y couler du béton à l'intérieur.After assembly of two adjacent panels according to the invention, a formwork 14 can be installed around the corner area 12 so as to pour concrete inside.
Enfin il est possible de revêtir les couches de béton 3A et 3B, soit en usine, soit à la fin de la construction, d'un revêtement de finition 15A et 15B.Finally, it is possible to coat the concrete layers 3A and 3B, either at the factory or at the end of the construction, with a finishing coating 15A and 15B.
Comme visible sur la figure 3, des ouvertures 16, 17 peuvent être ménagées dans l'ensemble du panneau de manière à y apposer en usine ou sur le site respectivement des fenêtres ou des portes. Le panneau ainsi fabriqué peut être facilement ancré dans le sol 15 en particulier grâce aux extrémités saillantes inférieures 18 des éléments de renfort 5 formant montants verticaux et raccordés à des éléments de construction tels que toiture, au moyen des extrémités saillantes supérieures 19 de ces mêmes éléments de renfort 5, qui servent également d'accroché lors de la manutention et du transport dudit panneau. Les éléments de renfort 8 horizontaux formant ceinture de la construction sont disposés, lorsqu'il existe des ouvertures prévues pour des fenêtres ou des portes, de part et d'autre de ces ouvertures dans le sens vertical. Chaque panneau peut, à lui seul, constituer le mur entier d'un bâtiment, l'assemblage de quatre panneaux selon l'invention permet de réaliser par exemple les quatre murs extérieurs d'une maison d'habitation, construite ainsi très rapidement.As shown in Figure 3, openings 16, 17 may be provided in the entire panel so as to affix factory or on the site respectively windows or doors. The panel thus manufactured can be easily anchored in the ground 15, in particular by virtue of the lower projecting ends 18 of the reinforcing elements 5 forming vertical uprights and connected to construction elements such as roofing, by means of the upper projecting ends 19 of these same elements. reinforcement 5, which also serve as hooked during handling and transport of said panel. The horizontal reinforcing elements 8 forming belt of the construction are arranged, when there are openings provided for windows or doors, on either side of these openings in the vertical direction. Each panel may, by itself, constitute the entire wall of a building, the assembly of four panels according to the invention allows for example the four outer walls of a dwelling house, built so quickly.
Les murs composites réalisés à l'aide des panneaux selon la présente invention, sont à la fois rigides et légers. L'épaisseur de l'âme en polystyrène peut être par exemple de l'ordre de 30 centimètres, l'épaisseur des couches de béton intérieur et extérieur 3A et 3B peut être comprise par exemple entre 2 à 3 centimètres environ.The composite walls made using the panels according to the present invention are both rigid and lightweight. The thickness of the polystyrene core may be for example of the order of 30 centimeters, the thickness of the inner and outer concrete layers 3A and 3B may be for example between 2 to 3 centimeters.
Enfin, pour une meilleure assise et une meilleure stabilité du panneau dans la construction, il peut être prévu des logements longitudinaux ménagés dans les tranches horizontales supérieure et/ou inférieure du panneau 1 et destinés à recevoir des poutres, par exemple en béton.Finally, for better seating and better stability of the panel in the construction, it can be provided longitudinal housing formed in the upper and / or lower horizontal slices of the panel 1 and intended to receive beams, for example concrete.
De tels aménagements peuvent en effet s'avérer utiles lorsque les panneaux vont supporter des couvertures d'un poids important. Such arrangements can indeed be useful when the panels will support heavy blankets.
